The future Jushin "Thunder" Liger trained at The Dungeon while competing for Stu Hart's Stampede Wrestling. Under his real name of Keiichi Yamada, the Japanese icon first worked for the Calgary promotion in 1987, but returned in 1989.

It was around the time of his second stint at The Dungeon that Yamada repackaged himself as Jushin Liger. Debuting under the name on April 24, 1989, Liger sported a full-body costume and his now-trademark mask. The gimmick would transform his career.

Liger would go on to have an astonishing 35-year career, during which he is estimated to have had over 4,000 matches. That The Dungeon had a hand in producing such a legendary performer speaks volumes for its legacy.

Liger's success was not solely limited to Japan either. Throughout the years, Liger made appearances for many wrestling companies, including WCW, TNA and ROH. Liger even made a one-off appearance for WWE at NXT TakeOver: Brooklyn 2015 - where he defeated Tyler Breeze.

Even though he only wrestled one match for the company, WWE announced in March that Liger would be inducted into the promotion's Hall of Fame in 2020. A fitting tribute to a professional wrestling legend.
